A concise usage guide that identifies common faults in everyday speaking and writing and offers practical corrections and stylistic guidance. Chapters treat literary taste, precise word choice, contractions, possessives, pronouns, number agreement, adverbs, conjunctions and correlatives, infinitives and participles, prepositions, the article, redundancy, double negatives, and verb‑subject agreement. Advice emphasizes clarity and economy, warns against pedantry, excessive foreignisms, and misplaced poetic diction, and recommends following good models. The treatment is brief and practical, with rules, illustrative examples, and an index for quick reference.
